插入数据
可以看到，我们刚创建的数据库 runoob 并不在数据库的列表中， 要显示它，我们需要向 runoob 数据库插入一些数据。
> db.runoob.insert({"name":"菜鸟教程"})
WriteResult({ "nInserted" : 1 })
> show dbs
local 0.078GB
runoob 0.078GB
test 0.078GB

删除数据库
db.dropDatabase()
删除当前数据库，默认为 test, 可以使用 db 命令查看当前数据库名称
查询集合
show tables
创建集合
db.createCollection(name, options)
name 创建的集合的名称
options （可选） 指定有关内存大小和索引的选项
删除集合
db.collection.drop()
向集合中插入文档
db.COLLECTION_NAME.insert(document)
> show dbs
admin 0.000GB
local 0.000GB
runoob 0.000GB
> use runoob
switched to db runoob
> db

> show tables
col
> db.col.insert({title: 'MongoDB 教程', description: 'MongoDB 是一个 Nosql 数据库'})
WriteResult({ "nInserted" : 1 })
查看已插入的文档
col 是集合名，如果该集合不在该数据库中， MongoDB 会自动创建该集合并插入文档
db.collection.find(query, projection)
query ：可选，使用查询操作符指定查询条件
projection ：可选，使用投影操作符指定返回的键。查询时返回文档中所有键值， 只需省略该参数即可（默认省略）
pretty() 方法以格式化的方式来显示所有文档
db.col.find().pretty()
更新文档
db.collection.update(
<query>,
<update>,
{
upsert: <boolean>,
multi: <boolean>,
writeConcern: <document>
}
)
参数说明：
query : update的查询条件，类似sql update查询内where后面的。
update : update的对象和一些更新的操作符（如$,$inc...）等，也可以理解为sql update查询内set后面的
upsert : 可选，这个参数的意思是，如果不存在update的记录，是否插入objNew,true为插入，默认是false，不插入。
multi : 可选，mongodb 默认是false,只更新找到的第一条记录，如果这个参数为true,就把按条件查出来多条记录全部更新。
writeConcern :可选，抛出异常的级别。
> db.col.find()
{ "_id" : ObjectId("5a13f8db577a5fb9bfdbec22") }
{ "_id" : ObjectId("5a14eec1619ae743f101f2b5"), "title" : "MongoDB 教程", "description" : "MongoDB 是一个 Nosql 数据库" }
{ "_id" : ObjectId("5a150f72619ae743f101f2b6"), "title" : "Mo", "description" : "Nosql" }
> db.col.update({"title": "Mo"},{$set: {"title": "oo"}})
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 })
> db.col.find()
{ "_id" : ObjectId("5a13f8db577a5fb9bfdbec22") }
{ "_id" : ObjectId("5a14eec1619ae743f101f2b5"), "title" : "MongoDB 教程", "description" : "MongoDB 是一个 Nosql 数据库" }
{ "_id" : ObjectId("5a150f72619ae743f101f2b6"), "title" : "oo", "description" : "Nosql" }
更新多条数据
>db.col.update({'title':'MongoDB 教程'},{$set:{'title':'MongoDB'}},{multi:true})
替换
save() 方法通过传入的文档来替换已有文档
db.collection.save(
<document>,
{
writeConcern: <document>
}
)
参数说明：
document : 文档数据。
writeConcern :可选，抛出异常的级别。
> db.col.find()
{ "_id" : ObjectId("5a13f8db577a5fb9bfdbec22") }
{ "_id" : ObjectId("5a14eec1619ae743f101f2b5"), "title" : "MongoDB 教程", "description" : "MongoDB 是一个 Nosql 数据库" }
{ "_id" : ObjectId("5a150f72619ae743f101f2b6"), "title" : "oo", "description" : "Nosql" }
> db.col.save({"_id": ObjectId("5a14eec1619ae743f101f2b5"),'title':'aaaa','description':'balabala...'})
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 })
> db.col.find()
{ "_id" : ObjectId("5a13f8db577a5fb9bfdbec22") }
{ "_id" : ObjectId("5a14eec1619ae743f101f2b5"), "title" : "aaaa", "description" : "balabala..." }
{ "_id" : ObjectId("5a150f72619ae743f101f2b6"), "title" : "oo", "description" : "Nosql" }
删除文档
remove()函数是用来移除集合中的数据
db.collection.remove(
<query>,
{
justOne: <boolean>,
writeConcern: <document>
}
)
参数说明：
query :（可选）删除的文档的条件。
justOne : （可选）如果设为 true 或 1，则只删除一个文档。
writeConcern :（可选）抛出异常的级别。
删除第一条找到的记录可以设置 justOne 为 1
db.COLLECTION_NAME.remove(DELETION_CRITERIA,1)
删除所有数据
db.col.remove({})
